7 Claims.-

This invention rel-atesto a slide buckle and has I special reference to a device adapted to be mounted on belts, straps, and the like, for the support of garments or other objects particularly on the person, or for otherwise detachably securing articles together.

More particularly, this invention relates to a slide buckle comprising a pair of slidably engaged sheet met-a1 frames in which one of the frames has side bars and cross bars connecting the side bars with ledges secured to and spaced from the side bars to extend. inwardly toward each other to form opposed channels when viewed in cross section, one of the cross bars presenting a strapengaging face inclined relative to the plane of the frame and the other of the frames comprising side bars engaging the opposed channels of the other frame to be guided in a longitudinal movement thereby. The cross bars connecting the side bars of the second mentioned frame form a strap-receiving slot, one of the cross bars thereof 1 co-operating with the inclined face of the cross bar of the first mentioned frame to clamp a strap threaded therebetween and through the strapreceiving slot in desired adjusted positions.

The buckle of the present invention is adapta- 1 ble for use with various types of objects particularly on the person and may be employed with slight variations not departing from the spirit of the invention, universally where detachable connections are desired to be made. However, in the drawings and in the following-description, the slide buckle is described and shown in its association with a belt, the belt being threaded beadjustably clamping the belt relative thereto. It

' will, of course, be readily apparent that various other uses may be made and that this invention is not to be limited to the specific uses herein described and illustrated.

Applicant contemplates the provision of a slide buckle formed of two slidably engaged sheet metal frames for the reception of the belt or strap threaded therebetween, the frame members cooperating to grip efiiciently and at the same time to permit of a ready adjustment. The belt or tween co-oper-ating slidably engaged frames for corpora- I 1936, Serial No. 95,053

ccnstruction being so devised as to give the maximum strength necessary for durability with a minimum weight of material.

One of the objects of this invention is to provide a buckle comprising a pair of slidably en' 5 gaged frames of the type hereinabove described in which a belt or strap threaded therethrough may be conveniently andeasily adjusted in either direction.

A further object of this invention is to provide a slide buckle comprising a pair of slidably engaged frames of the character indicated above in which the construction may be relatively inexpensive to manufacture, may be durable and simple in construction, and simple in threading. and manipulation.

Other objects andadvantages will hereinafter be more particularly pointed out and for a more complete understanding of the characteristic features of this invention, reference may now be had to the following description when taken together with the accompanying drawing, in which latter:

Figure 1 is a front elevational View of the buckle embodied in this invention in'its relation to a belt shown fragmentarily;

Fig. 2 is a view similar to Fig. 1 showing one end portion of the belt removed from the buckle;

Fig. 3 is a rear elevational view of the buckle, the belt in this instance not being shown;

Fig. 4 is a central longitudinal sectional view taken on the line 44 of Fig. 2 showing one end of the belt threaded in an initial position in dotted lines ready to be clamped;

Fig. 5 is a view similar to Fig. 4 showing the belt in dotted'lines in a clamped position;

Fig. 6 is a perspective View of one of the slidably engaged frames of the buckle of this invention;

Fig. 7 is a perspective view of the other slidably engaged frame of the buckle of this invention;

Fig. 8 isa View similar to Fig. 4 showing a modified form of buckle construction embodying the features of this invention;

Fig. 9 is a view similar to Fig. 6 of one of the slidably engaged frames of the buckle of Fig.8; and v Fig. 10 is a view similar to Fig. '7 of the other of the slidably engaged frames.

Referring now to the drawing and more particularly to Figs. 1 to 7, inclusive thereof, the construction therein shown comprises a pair of frame members Ill and II, the frame member I0 being preferably substantially rectangular in out-, line having side bars l2 and I3 connected by cross bars l4 and [5. The frame II is likewise preferably substantially rectangular in outline hav- 55 ing side bars 86 and I? connected by cross bars I8 and 19 forming a slot 29. The side bars and cross bars of the frame Iii are preferably embossed or, in other words, the face of the frame is raised providing a peripheral flange about the frame. This permits of the use of a minimum weight or gauge material to obtain a maximum rigidity.

The cross bar I5 of the frame I0 is preferably of substantial width and presents a belt-engaging face 2i raised above the embossed portion thereof and inclined relative to the plane of the frame. The length of the belt-engaging face 2| is substantially greater than the distance between the opposed inner edges of the side bars I2 and I3 so that a belt of maximum width threaded through the frame in engagement with the inclined face 2| will have the edges thereof rest against the faces of the side bars.

The frame It! is provided with ledges 22 and 23 preferably formed integrally with the lower edges of the side bars I2 and i3, respectively, and extending inwardly toward each other to form opposed channels when viewed in cross section. The channels receive the side bars I6 and IT of the frame and guide the frame in a longitudinal movement and in the direction of the plane of the frame, converging with respect to the inclined face ii.

The cross bars I8 and I9 are preferably of arcuate cross section having oppositely directed arcuate faces. The cross bar I8 of the frame II co-operates with the inclined face 2| of the frame it to clamp the belt 2 threaded therebetween and through the belt-receiving slot 20 in various desired adjusted positions. By reason of the fact that the cross bars I8 and I9 are formed of arcuate cross secton or are provided with arcuate faces, the engagement thereof with the belt will produce no marring or cutting effect on the belt. Further, the provision of arcuate members of this type reenforces and strengthens the frame as a whole. The particular direction of the arcuate faces provides a preferable relation between the belt and the frames I0 and II as is readih apparent from the drawing and particularly Figs.

l and 5. The belt is shown as being turned in two directions, the directions of the turns of the belt being the same as the direction of the arcuate faces of the cross bars.

When it is desired to clamp the belt in an adjusted position, a tension on the belt 24 provides a relative longitudinal movement of the frame members 56 and II in opposite directions, the frame it being in a fixed position since it is fixedly attached to one end of the belt and the other frame lI having relative movement therewith since the belt is threaded through the beltreceiving slot 2B and is pulled in the direction of the inclined face. The frame member II being directed in its movement in a plane parallel with the plane of the frame, the belt willbe urged againstthe inclined belt-engaging face and the arcuate face of the cross bar I8. The greater the tension on the belt, the firmer the belt is clamped between the engaging face of the co-operating cross bars because of the converging relation of the movable frames. The relation of the oppositely directed arcuate faces of the cross bars l8 and I9 of the frame II and the inclined cross bar 2| of substantial width permits a gripping of the belt 25 without marring or cutting irrespective of the tension placedthereon.

Thus, a desired clamping action is had without sharp edges or teeth being employed.

' 20a. The side bars and cross bars of the frame Illa are preferably embossed or, in other words,

the face of the'frame is raised providing a peripheral flange about the frame for the purpose of obtaining amaximum rigidity with the use of a minimum weight or gauge material.

The cross bar I5a of the frame Illa. is preferably of substantial width and presents a belt or strap engaging face Zla raised above the embossed portion thereof and inclined relative to The buckle of this embodiment, as shown, is preferably for use with an ordinary strap such as may be employed on luggage, brief cases, skates, and the like, and the free edge 2Ib is rolled to permit the free movement of a strap therearound as the free end portion of the strap extending from the buckle is pulled in a direction against that portion of the strap within and extending to the buckle, the rolled edge providing a fulcrum about which the strap is bent.

The frame Ida is preferably provided with ledges 22a and 23a formed integrally with the lower edges of the side bars I21; and I3a, respectively, and extending inwardly toward each other to form opposed channels when viewed in cross section. The channels receive the side bars Mia and Ila of the frame Ila and guide the frame in a longitudinal movement and in the direction of the plane of the frame, converging with respect to the inclined face ZIa.

The cross bars Illa and I90 preferably present portions which are inclined with respect to the plane of the frame, the edge portion I8bof the cross bar I8a bounding one side of the slot 20a being inclined in substantially the direction of the inclined face 2m of the frame I011. The cross bar I8 of the previously described embodiment and present cross bar I8a may both be said to have portions which are turned out of the normal flat plane of the frame, the function of both contemplating the provision of a strapengaging portion which will effectively clamp the strap yet will not prevent a sharp clamping edge. The edge I9b of the cross bar I9a bounding the other side of the slot 201 is turned out of the normal fiat plane of the frame in a direction opposite to that of the inclined edge IBb.

By reason of the fact that the cross bars I and I9 0. are formed with oppositely directed inclined faces, or portions which are turned out of the normal flat plane of the frame, the engagement thereof with the belt will, in substantially the same manner as in the previous embodiment, produce no marring or cutting effect on the belt. Further, the provision of these rolled or inclined edge reenforces and strengthens the frame as a whole. The belt or strap 24a is shown as being turned in two directions, the direction of the turn'of the belt being the same as the direction of the inclined faces of the cross bars. Since the clamping of the belt in an adjusted position in the framemembers of the buckle of this embodiment is thesame as that previously described in connection with the first mentioned embodiment, a description thereof would merely be repetition and is deemed unnecessary.

While but two embodiments of this invention are herein shown and described, it is to be understood that vari us modifications thereof may be apparent to i%e skilled in the art without departing from t e spirit and scope of his invention and, therrfnre, the same is only to be limited by the scope of the prior art and the appended claims.
